A man is in bed with his wife when there is a rat-a-tat-tat on the door.  He rolls over and looks at his clock, and it�s half-past three in the morning.

�I�m not getting out of bed at this time,� he thinks, and rolls over.  Then, a louder knock follows.  �Aren�t you going to answer that?�  says his wife.  So he drags himself out of bed, and goes downstairs.  He opens the door and there is a man standing at the door.  It didn�t take the homeowner long to realize the man was drunk. 

             �Hi there,� slurs the stranger.  �Can you give me a push�?

             �No, get lost, it�s half past three.  I was in bed,� says the man and slams the door. 

             He goes back up to bed and tells his wife what happened and she says, �Dave, that wasn�t very nice of you.  Remember that night we broke down in the pouring rain on the way to pick the kids up from the baby-sitter and you had to knock on that man�s house to get us started again?  What would have happened if he�d told us to get lost?�

             �But the guy was drunk,� says the husband.

             �It doesn�t matter,� says the wife.  �He needs our help and it would be right thing to do.�

So the husband gets out of the bed again, gets dressed, and goes downstairs.  He opens the door, and not being able to see the stranger anywhere he shouts,

�Hey, do you still want a push??�

� and he hears a voice cry out, �Yeah, please.�

             So, still being unable to see the stranger he shouts:  �Where are you?�

             And the stranger replies:  �I�m over here, on your swing.�
